This guy is just a mimic-er...right? Anyway, I recon he could've constructed a wire frame and mounted it to the bottom so that stupid blob would be supporting the slog.
I rather like the plain look of it. And I don't find the rocks too distracting either. When you're thinking about it too critically as an artist, which is sort of sad if your first thoughts are to compare yourself too it, it takes away from the whole "cool" factor.
